isLocked

Syntax

TF = isLocked(H)

Description

TF = isLocked(H) returns the locked status, TF,
for the PhaseShiftBeamformer System object™.

The isLocked method returns a logical value
that indicates whether input attributes and nontunable properties
for the object are locked. The object performs an internal initialization
the first time the step method is executed. This
initialization locks nontunable properties and input specifications,
such as dimensions, complexity, and data type of the input data. After
locking, the isLocked method returns a true value.
